Obviously, the described embodiments These are some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.
图1为本发明实施例提供的一种后视镜自动加热方法的流程示意图，如图1所示，本发明实施例提供了一种后视镜自动加热方法，包括：Figure 1 is a schematic flow chart of an automatic rearview mirror heating method provided by an embodiment of the present invention. As shown in Figure 1, an embodiment of the present invention provides an automatic rearview mirror heating method, which includes:
步骤S101，通过摄像装置采集到车主的摄像数据，并获取所述摄像数据中车主在车辆驾驶时的视线方向。Step S101, collect the camera data of the car owner through the camera device, and obtain the direction of sight of the car owner while driving the vehicle in the camera data.
具体地，车辆驾驶系统通过摄像装置采集到车主的摄像数据，并根据摄像数据获取到车主在摄像数据中，车辆驾驶时车主的视线方向，其中，车主的视线方向可以通过车主驾驶时的头部偏转角度确定。Specifically, the vehicle driving system collects the camera data of the car owner through the camera device, and obtains the direction of the car owner's sight when driving the vehicle in the camera data based on the camera data. The direction of the car owner's sight can be determined by the head of the car owner when driving. The deflection angle is determined.
步骤S102，当所述视线方向为后视镜方向时，检测所述车主保持所述视线方向的时长是否大于预设时长。Step S102: When the line of sight direction is the direction of the rearview mirror, detect whether the length of time the car owner maintains the line of sight direction is greater than a preset time period.
具体地，当检测到车主的视线方向为左右两边的后视镜方向时，检测车主保持后视镜方向的视线方向的时长是否大于预设时长，即检测车主是否长时间的查看后视镜中的交通情况，预设时长可以由车主设置，比如4秒、5秒等。Specifically, when it is detected that the direction of the car owner's sight is the direction of the left and right rearview mirrors, it is detected whether the length of time the car owner maintains the direction of the rearview mirror is greater than the preset time, that is, it is detected whether the car owner looks in the rearview mirror for a long time. Depending on the traffic situation, the preset time can be set by the car owner, such as 4 seconds, 5 seconds, etc.
步骤S103，当所述车主保持视线方向的时长大于预设时长时，通过所述摄像装置采集所述车主的面部表情，并对所述面部表情进行微表情分析，得到微表情分析结果。Step S103: When the car owner maintains the direction of his gaze for longer than a preset time, the camera device collects the facial expression of the car owner, performs micro-expression analysis on the facial expression, and obtains micro-expression analysis results.
具体地，当车主保持后视镜方向的视线方向的时长大于预设时长时，说明车主在长时间的查看后视镜中的交通情况，此时后视镜可能存在模糊的情况，也有可能是车主在观察交通情况，为了完成车辆转向、倒车等情况，为了确定后视镜是否存在模糊，则通过摄像装置采集车主的面部表情，并通过微表情分析技术分析车主的面部表情，可以得到在车主查看后视镜的过程中，车主的情绪变化。Specifically, when the car owner keeps his sight direction in the rearview mirror for longer than the preset time, it means that the car owner is checking the traffic situation in the rearview mirror for a long time. At this time, the rearview mirror may be blurred, or it may be blurred. When the car owner is observing the traffic situation, in order to complete the vehicle steering, reversing, etc., and to determine whether the rearview mirror is blurred, the car owner's facial expressions are collected through the camera device, and the car owner's facial expressions are analyzed through micro-expression analysis technology, and the car owner's facial expressions can be obtained. The car owner's mood changes while checking the rearview mirror.
步骤S104，获取预设的车主微表情集合，将所述微表情分析结果与所述车主微表情集合进行对比，当所述微表情分析结果与所述车主微表情集合匹配时，启动后视镜加热装置对后视镜进行加热。Step S104: Obtain the preset micro-expression set of the car owner, compare the micro-expression analysis result with the car owner's micro-expression set, and activate the rearview mirror when the micro-expression analysis result matches the car owner's micro-expression set. The heating device heats the rearview mirrors.
具体地，获取预设的车主微表情集合，其中，车主微表情集合可以由车主预先拍摄，然后上传的照片进行面部表情采集得到，包括车主不满、疑惑、好奇、生气等情绪，具体表现在微表情上表现为眉毛收紧、嘴唇紧张、眼睛张大等特征，当微表情分析结果与车主微表情集合匹配时，说明用户处于上述情绪中，需要从后视镜中获取到信息，后视镜处于模糊状态，则启动后视镜加热装置对后视镜进行加热，保证车主能及时获取到当前的交通状况。Specifically, a preset set of micro-expressions of the car owner is obtained. The set of micro-expressions of the car owner can be pre-photographed by the car owner and then collected by uploading photos to collect facial expressions, including the car owner's dissatisfaction, doubt, curiosity, anger and other emotions, which are specifically reflected in the micro-expressions. The expression is characterized by tightened eyebrows, tense lips, widened eyes, etc. When the micro-expression analysis results match the car owner's micro-expression collection, it means that the user is in the above emotions and needs to obtain information from the rearview mirror, which is in If the vehicle is in a blurry state, the rearview mirror heating device will be activated to heat the rearview mirror to ensure that the car owner can obtain the current traffic conditions in a timely manner.
本发明实施例提供的一种后视镜自动加热方法，通过摄像装置采集到车主的摄像数据，并获取摄像数据中车主在车辆驾驶时的视线方向；当视线方向为后视镜方向时，检测车主保持视线方向的时长是否大于预设时长；当车主保持视线方向的时长大于预设时长时，通过摄像装置采集车主的面部表情，并对面部表情进行微表情分析，得到微表情分析结果；获取预设的车主微表情集合，将微表情分析结果与车主微表情集合进行对比，当微表情分析结果与车主微表情集合匹配时，启动后视镜加热装置对后视镜进行加热。这样能够更智能的根据车主的需求进行后视镜加热装置的开启，进而也节省了能源。An embodiment of the present invention provides a method for automatically heating rearview mirrors, which collects the camera data of the car owner through a camera device, and obtains the direction of the car owner's line of sight while driving the vehicle in the camera data; when the line of sight direction is the direction of the rearview mirror, detect Whether the car owner maintains his/her gaze direction for longer than the preset time period; when the car owner maintains his/her gaze direction for longer than the preset time period, the facial expression of the car owner is collected through the camera device, and micro-expression analysis is performed on the facial expression to obtain the micro-expression analysis results; Obtain The preset car owner's micro-expression set compares the micro-expression analysis results with the car owner's micro-expression set. When the micro-expression analysis results match the car owner's micro-expression set, the rearview mirror heating device is started to heat the rearview mirror. In this way, the rearview mirror heating device can be turned on more intelligently according to the needs of the car owner, thereby saving energy.

Generally speaking, the higher the heating demand degree, the longer the heating time after the heating device is started.
另外，当未获取到预设的车主微表情集合时，说明车主可能并未预设对应的微表情集合，则获取外界信息，根据外界信息确定是否需要加热，通过外界信息确定对应的加热需求程度，当加热需求程度大于预设等级时，说明后视镜处于模糊状态，则启动后视镜加热装置对后视镜进行加热。In addition, when the preset set of micro-expressions of the car owner is not obtained, it means that the car owner may not have preset the corresponding set of micro-expressions. Then, external information is obtained, whether heating is required based on the external information, and the corresponding heating demand level is determined based on the external information. , when the heating demand is greater than the preset level, it means that the rearview mirror is in a blurry state, and the rearview mirror heating device is started to heat the rearview mirror.
本发明实施例通过外界信息智能的调整加热装置启动后的加热时长，使得车辆的后视镜加热过程更智能，也更加节省能源。The embodiment of the present invention intelligently adjusts the heating time after the heating device is started through external information, making the vehicle's rearview mirror heating process more intelligent and more energy-saving.
